Crushed ore heap leaching involves reducing ROM ore to a predetermined optimal target size distribution, sometimes with topsizes as small as 12.5 mm (0.5 in.) or even finer through multiple stages of crushing. Crushing increases surface area and mineral liberation which, in turn, result in higher, more economic recovery.

2.1 Leaching. Most copper leaching is done by piling broken ore (∼0.5% Cu) into flat-surface, 3–10m high, 10 4 –10 5 m 2 heaps of ore and then sprinkling dilute sulfuric acid lixiviant on to the heap surface. The lixiviant trickles down through the heap and leaches copper from its minerals to produce a pregnant leach solution containing 1–5kg Cum −3.
